Chapter 3:  General Operating Principles

 

 

Before you start using the DES-42 pneumatic heat seal machine, read this chapter to become 
familiar with general principles of all heat sealing operations and to learn the following operating 
procedures that are specific to the DES-42. 

 

Actuating the DES-42 

 

Using the Emergency Release pushbutton 

 
 

General Heat Sealing Principles

 

 
All heat sealing processes involve three main factors, as follows: 

 

The temperature of the platens; 

 

The inter-platen pressure; 

 

The cycle dwell time. 

 
To set tolerances and control values for platen temperature, inter-platen pressure, and cycle dwell 
time, use the DES-42 control panel.  For more information, see Chapter 4, 

Using the DES-42 

Control Panel

.  You can also use the control panel’s digital display area to monitor the actual 

platen temperatures and air line pressure.  The exact settings of the three main factors depend on 
the requirements of your specific fusing or transfer application. 
 
 

Actuating the Heat Seal Machine

 

 
To actuate the DES-42: 

 

Position top platen over one of the bottom platens and depress the black pushbutton 
labeled “Start Cycle” located on the handle simultaneously with one of the black 
pushbuttons labeled “Start Cycle” located on either side of the swivel head.  Machine will 
cycle ONLY when the top platen is in position directly over a bottom platen. 

 
 

Using the Emergency Release Pushbutton

 

 
To interrupt the DES-42 during operation: 

 

Push one of the red “Emergency Release” pushbuttons located on either side of the swivel 
head.  This safety feature bypasses the timer and immediately opens the press in case of an 
emergency.  Only one red pushbutton need be depressed to interrupt cycle.  Also, the 
press should open immediately if the power switch is turned “OFF”, or if the machine 
power cord is unplugged.
